Amazingly Stepanek has won all four of their career matches so he'll be feeling pretty confident heading into this one. The Czech beat Fish back in 2007 when he was still one of the best in the world, enjoying a 7-5, 7-6(3) win in Cincinnati. However he's continued to beat the American recently, even defeating him 6-3, 6-1 in Brisbane last year.

However Fish was a runner-up in Cincinnati two years ago and he was in fine form yesterday, easing past Carlos Berlocq 6-3, 6-1 in the second round.

"I felt like I played as well today as I have all summer," Fish said. "This guy (Berlocq) is a good player, really good player. If you're not on top of your game, you're going to be in a lot of trouble. I could still be out there, no doubt, and he could beat me. I felt like I was in control the entire match. That's satisfying, for sure."

Stepanek showed in Toronto that he's still very dangerous on his day, defeating Juan Martin Del Potro in the first round and earlier this week he took out eighth seed Juan Monaco 7-6(2), 6-1 in the second round.
